This invention relates to certain new and useful improvements in apparatus for clean- 111g 11'011 bars.v

In the heat treatment of iron bars, plates ers adjacent each end thereof with a pair of intermediately positioned cleaning rollers of stone or the like that are positively rotated in directions reverse to the travel of the bars or 7 plates overthe table for removing crust or scale from the surfaces of the bars or plates,

suction apparatus being associated with the grinding or cleaning rollers for the collection and disposal of refuse cleaned from the bars or plates. V A V A 'still further objectof the invention is to provide apparatus of the foregoing character with laterally positioned guidermembers be tween which the bars or plates are fed for m directing the latter in the proper course through theapparatus. j

With the above and other objects in view that will become apparent as the nature of the invention is better understood, the same 7 consists in the novel form, combination and arrangement of parts hereinafter more fully -described, shown in the accompanying drawjings and claimed. V

Figure 5 is a vertical cross-sectional view taken on line 5- 5 of Figure 1, showing the suction devices associated with the cleaning or grinding'rollers with'sep arate motor drives for each roller; and

Figure 6 is a vertical cross-sectional view 7 7 taken on line 6-6 of Figure 1, showing the bracket hanger from the bearing of the upper adjustable cleaning roller for the support of the driving motor therefor.

Referring morein detail to the accompanying drawings, there is illustrated an appara- I tus for cleaning iron bars for the removal of crust or scale therefrom and including a table or bed formed of a skeleton frame having side rails 10 connected by end cross rails 11 and carrying supporting legs 12. A plurality of groups of bed rollers 13 extending transversely of the frame structure are journalled at their ends in the side rails 10 and are retained in position by bars 14 shownin Figure 2, the bedrollers 13 facilitating passage of bars or plates over the bed frame.

A pair of feed rollers for the bars or plates is arranged adjacent each end of the bed frame and cleaning or grinding rollers are associated with the bed frame intermediate the feed rollers. Each pair of feed rollers and the structure of the bed frame interinediately associated therewith includes a rectangular leg brace 1 1- depending from each side rail 10 and a rectangular frame rising above each side rail over the leg brace including corner posts 15 connected attheir upper end by a cross head 16 while the opposite rails 10 are connected by a head plate 17 the head plate, at the bar or plate entrance end of the bed frame being closed as shown in Figure 2 while the head plate associated with the feed rollers at the outlet end of the bed frame is open as at 17a. A feed roller 18 has the shaft 19 to which it is fixed journalled in the .side

'rails' lO between the corner posts 15 of the upper structure and carries a pulley upon one projecting end thereof that has a belt connection 20 with a motor 21, mounted upon a floor or other support. The upper roller 22 of each pair of feed rollers as shown in Flgures 1 and 4 is journalled at its end in blocks 24 that are vertically slidable in the corner posts 15 and each block bearing 24 is normally tensioned in a downward direction by a pan of coil springs 25 for moving the feed roller 22 toward the feed roller 18.

The cleaning or grinding rollers are arranged transversely of the side rails 10 intermediate the end feed rollers and the supporting structure for the cleaning or grinding rollers include a depending rectangular leg brace 26 carried by each side rail with upstanding corner posts 27 connected at their upper ends by' cross bars 28 forming side rectangular frames connected by cross bars 29. A lower cleaning or grinding roller 30 of stone or the like has its shaft ends 31 journalled in bearings .30 inthe side rails 10 below the posts 27 and one projecting end of the shaft 31 as shown in Figures 1 and'6 carries a pulley 32 having a belt connection 33 with a motor 34 mounted upon a floor or other support. An upper cleaning or grinding roller 35 of stone or the like has the shaftends 36 thereof journalled in bearing blocks 37 and 38 that are verticaly slidable between the pairs of corner guide posts 27, the bearing blocks 37 and 38 each carrying an upstanding strap .39 to which the lower end of an adjusting screw 40 is loosely connected as at 41, the upper end of the screw having a nut or handle 42 threaded thereon and engaged with the cross bar 28 for vertically shifting the block bearings 37 and 38 between the guide posts 27. Coil springs 43 are positioned between the bearing blocks 37 and 38, and the cross heads 28 for normally influencing the bear: ing blocks and roller 35 carried thereby in a downward direction, the loose connection 41 between the adjusting screws and block bearings permitting limited upward movement of the upper roller 35 against the tension of said springs, when a'ba r or plate is passed between the rollers 30 and 35. The cleaning or grinding rollers 30 and 35 are independently driven, the roller 30 being operated by the motor 34 and as shown in Figure 6, block bearing 38 carries a depending hanger bracket 44 for the support of a motor 45 that has a belt connection 46 with the pulley 47 upon the shaft end 36 that carries the roller 35, the bracket mounting for the motor 45 maintaining constant relationship between the motor and roller 35.

Suction devices are associated with the rollers 30 and 35 for the collection of scale and crustatious materials cleaned from the bars or plates, a suction nozzle head 48 being associated with-the lower roller 30 and carried by the cross bar 49 secured at its ends to the frames 26. A suction nozzle 50 is associated with the upper movable roller 35 and iscarried by the cross bar 51 attached at its ends to the straps 39 upon the bearing blocks 37 and 38. To protect persons at the work inlet end of the apparatus, from particles of material that may escape the suction nozzle and also in event of breakage of the grinding or cleaning rollers, an upstanding guard 52 is carried by the frame structure supporting the feed rollers at the inlet end of the apparatus as shown in Figures 1 and 2.

The bed of the apparatus is of a width to permit a pair of horizontally aligned bars or plates to be simultaneously fed to the apparatus as well as a single bar or plate and centering or guide devices are provided for directing the bars or plates to the feeding and cleaning rollers. Asshown in Figures 2 and 3, a cross bar 53 extends between the side rails 10 in advance of each set of rollers and said cross bar 53 is longitudinally slotted, as at54. Guide blocks 55, preferably of the form illustrated in Figure2 are slidable upon the cross bar 53, each block having a depending lug 56 depending into and guided by the slot 54 in the crossbar 53. Each guide block 55 is carried by a screw 57 freely extending through an opening in the guide rail-10 with the nut 58 threaded upon its outer end to limit inwardly sliding movement of the'block 55, the outer end of the block carrying guide pins 59 extending through the side rails and surrounded by coil springs 6'0 between the side rails and block for normally influencing the guide blocks toward the central longitudinal axis of themachine bed.

From the above detailed description of the invention, it is believed that the construction and operation thereof will at once be apparent, it being noted that a bar plate is fed over the bed rollers 10 between the guide blocks 55 and delivered by the first set of feed rollers to the intermediately positioned cleaning or grinding rollers. The cleaning or grinding. rollers are caused to rotate in directions reverse to the path of travel of the bar plates for the effective removal there-from of scale or crustatious coatings. The rollers 30 and 35are separately driven and the normal position of the upper roller relative to the lower roller is controlled by the adjusting screws 40, the feed rollers at the outlet end of the apparatus operating to deliver the bar or plate therefrom. The guide blocks 55 center the bar plate in its travel through the apparatus and they may be adjusted to accommodate the lateral positioning of a pair of bars or plates for simultaneous treatment.

While there is herein shown and described the preferred embodiment of the. invention, it is nevertheless to beunderstood that minor changes maybe made therein without departing from the spirit and scope of the invention as claimed. 1 f

What is claimed is Apparatus of the character described, comprising a frame bed, a set of feeding rollers adjacent each end thereof, a set of cleaning rollers intermediate the end rollers,'means for driving one roller of each set of feed rollers, separate drives for each of the cleaning rollers, a suction device associated with each cleaning roller, the drive and the suction device for theshiftable cleaning roller being movable therewith, and means for guiding bars or plates through the apparatus including a pair of transversely shiftable blocks, springs for moving the blocks toward each other, and means for limiting movement of the blocks.
